[PATCH v2 0/3] add liblzma support

[Jonathan Nieder <jrnieder@gmail.com>]

This was the motivation for me to start working on dpkg in the first
place.  As long as /usr/bin/lzma is an essential commmand, it is
difficult to uninstall it even for a moment to replace it with an
alternative implementation.

Unfortunately, liblzma does not provide a very convenient API yet.
The good news is that the experience from implementing this should
help determine what its higher-level API looks like once it’s written.
